Abstract

The present invention relates to a process for producing mixture of fuel components, which process comprises providing a feed of biological origin; subjecting said feed of biological origin and a hydrogen gas feed to a single step of hydroprocessing in the presence of a catalyst system comprising dewaxing catalyst to form a mixture of fuel components. The present invention relates also to an apparatus for producing a mixture of fuel components from a feed of biological origin. The invention relates also to the use of the fuel components.

First claim

The invention claimed is:

1. A process for producing a mixture of fuel components, wherein the process comprises
providing a feed of biological origin selected from tall oil, crude tall oil, resins and resin acids obtained from plants, and bio-oil from hydropyrolyzed wood;
subjecting said feed of biological origin and a hydrogen gas feed to a single step of hydroprocessing in the presence of a catalyst system comprising a NiW catalyst supported on zeolite-Al 2 O 3 , wherein the volume ratio of hydrogen gas feed to feed of biological origin is 100:1 to 1250:1 normal liter/liter, to form a mixture of fuel components,
said NiW catalyst supported on zeolite-Al 2 O 3 effecting the hydroprocessing by hydrodeoxygenating, hydrodesulfurizing, isomerizing, ring opening and cracking the feed of biological origin, and
separating from the mixture of fuel components a fraction comprising C17 and higher hydrocarbons and recycling the fraction back to the feed of biological origin and/or to the step of hydroprocessing.

2. The process according to claim 1 , wherein the catalyst is diluted with an agent selected from silicon carbide, aluminium oxide, glass beads, less active similar catalyst and inert ingredients.

3. The process according to claim 1 wherein the catalyst system optionally comprises at least one guard bed.

4. The process according to claim 1 wherein an additional sulphur feed is fed to the step of hydroprocessing.

5. The process according to claim 1 wherein hydrogen is recovered and recycled back to the step of hydroprocessing.

6. The process according to claim 1 wherein the step of hydroprocessing is carried out at a temperature range from about 280° C. to about 500° C.

7. The process according to claim 1 wherein the step of hydroprocessing is carried out at a pressure of about 30 to about 200 bar.

8. The process according to claim 1 wherein the WHSV of the feed material is in the range of about 0.4 to about 3.

9. The process according to claim 1 wherein any component can be isolated from the mixture of fuel components obtained.

10. The process according to claim 1 , wherein the process further comprises a hydropolishing step for treating the obtained mixture of fuel components.

11. A process for producing mixture of fuel components, characterized in that the process comprises
providing a feed of biological origin;
subjecting said feed of biological origin and a hydrogen gas feed to a single step of hydroprocessing in the presence of a catalyst system comprising NiW catalyst supported on zeolite-Al 2 O 3 to form a mixture of fuel components,
said NiW catalyst supported on zeolite-Al 2 O 3 effecting the hydroprocessing by hydrodeoxygenating, hydrodesulfurizing, isomerizing, ring opening and cracking said feed of biological origin, and
separating from the mixture of fuel components a fraction comprising C17 and higher hydrocarbons and recycling the fraction back to the feed of biological origin and/or to the step of hydroprocessing.

12. The process according to claim 11 , characterized in that the feed of biological origin is selected from the group consisting of
i) any kind of fats, any kind of waxes, plant fats, plant oils, plant waxes; animal fats, animal oils, animal waxes, fish fats, fish oils, fish waxes, and
ii) fatty acids or free fatty acids obtained from plant fats, plant oils, plant waxes; animal fats, animal oils, animal waxes; fish fats, fish oils, fish waxes, and mixtures thereof by hydrolysis, transesterification or pyrolysis, and
iii) esters obtained from plant fats, plant oils, plant waxes; animal fats, animal oils, animal waxes; fish fats, fish oils, fish waxes, and mixtures thereof by transesterification, and
iv)) metal salts of fatty acids obtained from plant fats, plant oils, plant waxes; animal fats, animal oils, animal waxes; fish fats, fish oils, fish waxes, and mixtures thereof by saponification, and
v) anhydrides of fatty acids from plant fats, plant oils, plant waxes; animal fats, animal oils, animal waxes; fish fats, fish oils, fish waxes, and mixtures thereof, and
vi) esters obtained by esterification of free fatty acids of plant, animal and fish origin with alcohols, and
vii) fatty alcohols or aldehydes obtained as reduction products of fatty acids from plant fats, plant oils, plant waxes; animal fats, animal oils, animal waxes; fish fats, fish oils, fish waxes, and mixtures thereof, and
viii) recycled food grade fats and oils, and fats, oils and waxes obtained by genetic engineering,
ix) dicarboxylic acids or polyols including diols, hydroxyketones, hydroxyaldehydes, hydroxycarboxylic acids, and corresponding di- or multifunctional sulphur compounds, corresponding di- or multifunctional nitrogen compounds,
x) compounds derived from algae,
xi) terpene-based compounds obtained from plants, terpene oils, distillation bottoms from terpene distillation and flavorants and/or fragrance industry,
xii) resins, resin acids or sterols obtained from plants, bio-oil from hydropyrolyzed wood, Fischer-Tropsch wax, and
xiii) mixtures of said feeds of biological origin.

13. The process according to claim 11 , characterized in that the feed of biological origin is selected form the group consisting of fish oils such as Baltic herring oil, salmon oil, herring oil, tuna oil, anchovy oil, sardine oil, and mackerel oil; plant oils such as rapeseed oil, colza oil, canola oil, tall oil, crude tall oil, sunflower seed oil, soybean oil, corn oil, hemp oil, linen seed oil, olive oil, cottonseed oil, mustard oil, palm oil, peanut oil, castor oil, Jatropha seed oil, Pongamia pinnata seed oil, palm kernel oil, and coconut oil; and animal fats such as lard, tallow, rendered lard and rendered tallow and waste and recycled food grade fats and oils, as well as fats, waxes and oils produced by genetic engineering; animal waxes such as bee wax, Chinese wax (insect wax), shellac wax, and lanoline (wool wax); plant waxes such as carnauba palm wax, Ouricouri palm wax, jojoba seed oil, candelilla wax, esparto wax, Japan wax, rice bran oil, terpenes, terpineols, triglycerides and mixtures thereof.
